I am quite certain a Russian visitors visa requires a return ticket date. It seems obvious to me that the entourage either...
A) Was not all comprised of guys who had flown in (ie: some people had no tickets.....not all)
B) They had tickets and just needed to "move them up" because they were in a hirry. I suppose it sounds less miraculous that way.
C) Its completely made up.
I think its B. But A is viable if, Sandersons possie really rolls that deep?!
